What do sclerenchyma and collenchyma have in common? A). They are both thin-walled.

B). They are both dead cells.

C). They both function for support.

D). They both function for food production and storage.

C). They both function for support

Explanation:

There are three types of ground tissues in plants namely: parenchyma, collenchyma and sclerenchyma. PARENCHYMA tissues are made up of living cells whose primary function is to help in the photosynthetic process and store sugar.

COLLENCHYMA is another tissue made up of living cells but have a thin primary cell wall. They give structural support to some inner plant parts. Lastly, SCLERENCHYMA are the only type of tissues with dead cells that possess a thickened secondary cell wall, hence, their major function is SUPPORT. From the observation of the functions of these tissues, one similarity between collenchyma and sclerenchyma is that "they both FUNCTION IN SUPPORT"

this protocol provides a detailed procedure for agarose-based ip to purify and enrich the protein of interest.

i think a) betsy can donate only blood to mark is correct because, mark and betsy have the same blood type. whereas nobody else has b+ blood so betsy can't donate to them.
